performer RPM isn't a bad intake for that setup, it'll give up a few ftlbs but if its a bargin I'd get it. the bad thing is that you can't run EGR- which helps milage a little bit. And I'd go with a slightly bigger cam than the one mentioned- the 204/204 cam is a GREAT cam for a truck.

Meet me at the border with $2000 and take home a pro-built 383" long block. You will smile every time you drive it.

thnx, jack vines

He said its the RPM intake... they're good to more like 6500. I would stick with a performer.

All things equal, stroking a 350 to a 383 will keep the same peak HP but add torque and shift both the torque and hp curves lower; more torque available early in the RPM band is a great thing for trucks.

Talk to a local machine shop that sells shortblocks. You can usually buy 350 shortblocks for $800 or so, so they might be willing to work a deal that includes a couple hundred bucks more to trade your 350 core for a 383. Throw some Vortecs on it with a mild cam and a performer intake and you have a nice torquey truck engine. Nothing wrong with a 350, but cubes are king.

Take a look at this photo. It compares a 350 to a 383 with Vortec heads and a 196/204 cam. Same heads, same compression, same cam, just different displacement. As you can see they both peak at 300 hp, but the HP is found lower on the 383 and there is an additional 30-40 lb-ft of torque down low.

the engine needs an overhaul anyways so i'm going to do something with it. I've located a performer rpm intake for a reasonable price, good intake on a 383?

you may want to get the 4.11's in there and a OD transmission. It'll be a much better daily driver. Then I'd stroke the engine to a 383 and add some vortec heads with a performer intake and a 256 cam.

Put the 4.11 gears in and you may decide you don't need any more motor.

350 vs 383 stroker

ok, i've read a lot of different opinions on this, hopefully someone can shed some light on this for my application.

I have a 77 chev c10 with what appears to be a basically stock 350.
its paired with a turbo 350 which i think has a kit in it. I've also got a set of 4:11 gears that came new in a box with the truck. i want to get as much out of this 350 as i can without spending a fortune. I'd like to stick around the $2000 mark under the hood. Am i better to build a 350 or a 383? Lets also remember i'm no mechanic but i know a few people who are if i need them
